+title: GLib 2.25 Installation on Ubuntu 16.04
+---
+
+Introduction
+-------------
+In this article we will look at installation of Glib 2.25 installation on Ubuntu 16.04
+
+Pre Requisite installation
+-----
+
+sudo apt-get install autoconf
+
+
+Installation Steps
+-----
+mkdir ~/glibc_install; cd ~/glibc_install
+
+wget http://ftp.gnu.org/gnu/glibc/glibc-2.25.tar.gz
+
+tar zxvf glibc-2.25.tar.gz
+
+cd glibc-2.25
+
+mkdir build
+
+cd build
+
+../configure --prefix=/opt/glibc-2.25
+
+make -j4
+
+sudo make install
+
+export LD_LIBRARY_PATH=/opt/glibc-2.25/lib
+
+If OS does not support the glibc version for example 2.25 that you require . Then installing glibc in default prefix may cause the system to become unusable . This is because  glibc consists of many pieces (200+ shared libraries) which all must match. One of the pieces is ld-linux.so.2, and it must match libc.so.6, If all libraries do not match it would actually cause the system to be unusable as glibc is a very critical library . Hence its preferable to install glibc in alternate prefix
+
+Errors
+
+- ld.so.conf errors
+
+mkdir -p /opt/glibc-2.25/etc ;  touch /opt/glibc-2.25/etc/ld.so.conf
